There is a fuller article in the Huffington Post :
Body Found In Aircraft Landing Gear At Heathrow Airport
A spokeswoman said: "Last night at approximately 8.40pm a person was detected scaling the perimeter fence at Cape Town International Airport (CTIA).
................. Interesting as the aircraft was airborne at 2032.
BA said it was liaising with South African authorities over the discovery, which was made at about 06:25 BST on Thursday.
............... and landed at 0637.
I am amazed that anyone could imagine that they could survive 11 hours at temperatures down to -65', and saddened that anyone could be so desperate as to try.
